WINDOW.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed OCObSl 24, 1906. Serial No. 340,268.

ToaZZ whom, t may concern:

Be it known that I, VILFRID H. BARRIERE, a citizen of the United States,residing at lVorcester, in the county of Vorcester and State ofMassachusetts, have invented a new and useful vWindow, of whichthefollowing is a specification. v

This invention relates to improvements in vertically movable windowsashes, the principal objects thereof being to provide improved meanswhereby when the sash is raised it can positively be held in positionwithout moving the sash itself laterally; also to provide this means inthe form of a mov-v able strip so constructed that tight joints with thewindow sash will be maintained at all times without involvingcomplicated construction or mechanism that will readily get out of orderin use.

Vindows having sashes constructed according to this invention areespeciallyapplicable to electric and railway cars and in similar places.They can also be used in various kinds of carriages, lunch wagons, andin all kinds of buildings.

-Reference is to be had to the accompanying drawings, in which Figure 1is a front inside elevation of a window exhibiting the principles of myinvention, Fig. 2 is a perspective sectional view of a portion of thesame on an enlarged scale. Fig. 3 is a transverse sectional view of amodihcation showing the parts in a different position, and on a stilllarger scale. Fig. 4 is a view similar to Fig. 1 showing a third way inwhich the invention may be car ried out. Fig. 5 is a fragmentary view ofparts shown in Fig. 4 on an enlarged scale, and Fig. 6 is a transversesectional view on the line 6-6 of Fig. 5.

Heretofore sashes for windows have been constructed having a holdingstrip formedin a stationary position thereon, and adapted to engage overa stationary ledge on a window sill. In these constructions it isnecessary to move the sash in and out in order to fix it in raisedposition and release it theree from. One of the advantages of thepresent invention is that this is avoided, and the sash can be raisedand lowered in tight guides; whereas in the constructions above referredto the guides had to be supplemented by springs or the like to permitthe lateral motion of the sash therein. In carrying out the presentinvention, these springs and all equivalents thereof are entirelyavoided.

These results are accomplished by employing a movable holding strip ordevice which can be projected out over the ledge independently of theposition of the sash. The invention can be carried out byusing one ofthese'strips preferably on the outside of the Window or by using one onthe outside and one on the inside.

Referring first to Figs. 1 and 2, it will be seen that the particularembodiment of the invention which is illustrated therein comprises asash 1.0 which may be in general of any ordinary or desiredconstruction. This sash is preferably provided .with springs or weightsfor assisting in raising it, and I have shown a pair of downwardlyextending projections 11 having perforations for receiving cords, wires,or the like 12, which may be connected with springs in casings 13, orwith weights or any other equivalent devices for assisting in raisingthe sash. These parts are so located as to efficiently accomplish thedesired result.

On the window sill either on the outside or inside thereof, or both, isa ledge 14 which is preferably stationary, and may be located upon aplate 15 resting on the sill.

Movably mounted on the sash itself, and preferably pivoted thereon, is aholding device or strip 16. This strip, as shown in Fig. 3, is intendedto normally remain entirely within the surface of the sash itself, notprojecting therefrom at any oint. At points conveniently located witrespect to the pivot and near the opposite ends of the strip are springs17 for normally and yieldingly holding the strip in this position.

When the sash is raised and it is desired to hold it in raised position,a button 18 or 180 located in convenient position is manipulated fromthe inside of the sash. This button has a projection 19, engaging a pin20 on the strip 16 to force the latter outward into the positionindicated in Fig. 2. Then the sash can be slightly lowered, and thestrip drops down over the ledge 14 and holds the sash in raisedposition. It will be noticed that the projection 19 is provided with aslot 190, and that a pin 21 mounted on the projection 20 assists inguiding the same, and limits the motion thereof in both directions,allowing the spring 181 or 182 to force the button back iiush with thesurface of the sash while the strip 16 is in the position shown in Fig.2.

When the holding strip is forced outwardly IIO beyond the surface of thesash it is desired that it should engage the ledge 14 in such a mannerthat it not only supports the sash, but produces a tight joint. Forthese purposes the holding strip is provided. with a notch 22 which isadapted to fit over the ledge, and has a shoulder engaging the top ofthe ledge to hold the sash. It thus accomplishes both of thesefunctions.

At the top of the holding strip it is provided with another notch 23,which, when the strip is withdrawn inside the surface of the sash, doesnot necessarily form a tight joint,'for the reason that the sash at thistime is intended to be lowered within the casing, but when the stripsprings outwardly, as described, the notch fits a projection 24 whichextends across the sash and forms a tight joint at this point. When itis desired to lower the sash, all that has to be done is to raise thesame sufficiently to allow the lower edge of the holding strip to movethe top of the ledge 14. The spring 17 then restores the holding stripto normal position, and the sash can be lowered within the casing. Theparts so far described are found in both Figs, 2 and 3. The former,however, represents a construction in which the inside part of the sashis wood, a forging 240 being employed to support the projection 24 andspring 17. In Fig. 3 a casting 241 serves these purposes and alsosupports the button 180 which in this case has a flange 183 to help holdit in position. The forked spring 182 also assists in holding the buttonin place.

. It is to be noted that the window is proe vided with tight guides 25for preventing lateral motion of a sash provided with a holding stripfor engaging a ledge, such as the ledge 14. In this case the guideprevents all lateral motion, and thereby permits the sash and frame tobe constructed with a tight joint.

In the form shown in Figs. 4, 5 and 6, a

pair of holding strips 16 are employed, beingY of similar shape to thatshown in figures above described. Instead of having a button tomanipulate the holding strips, they are provided with a pair ofprojections 26 which extend inwardly so as almost to engage each otherwhen the two strips are drawn into a position iiush with the outer facesof the sash by the springs 17 Located in the frame and adjacent to thepath of the projections 26 are a pair of pins 27. These pins aremountedon rods 2S which are adapted to slide in guides 29 in the window casing.A lever 30 connects the two rods and is pivoted at a point between them.A knob or handle 31 extends from said lever to the outside of thecasing, all these parts except the knob preferably being located withinthe casing.

When the sash is raised, the knob is turned in such a manner as to forcethe two pins inassess Wardly. They will then be in position to beengaged by the projections 26 when the sash is lowered. Therefore, theyautomatically force the projections and the holding strips outwardly asindicated in dotted lines in Fig. 6. Springs 32 are employed to forcethe rods back to such position that the pins will normally not engagethe projections.

While I have illustrated and described in detail three forms in which myinvention may be embodied, I am aware that many modifications may bemade therein without departing from the principle thereof or exceedingthe scope of the claims. Therefore, I do not wish to be limited to theparticular construction shown or described, but

What I do claim is:-

1. The combination with a window casing having an inwardly and anupwardly slanting ledge, of a sash having an outwardly movable holdingstrip provided with a notch on its inner surface for resting on andfitting the top edge of said ledge, whereby the top of the ledge willsupport the strip and form a tight joint therewith.

2. The combination with a window casing having an inwardly extendingledge, of a sash having a downwardly extending projection near its outersurface, and an outwardly movable holding strip under said projectionprovided with a` notch for resting on and fitting the top of said ledgeand forming a tight joint therewith, said strip also having a notch forfitting and forming a tight joint with said downwardly extendingprojection on the sash when either in retracted or expanded position.

3. In a window sash, the combination of a pivoted holding strip, aspring for normally holding. the strip near the surface of the sash, anda pin movable independently of the strip for forcing the strip beyondthe surface of the sash.

4.k In a window sash, the combination of a pivoted holding strip, aspring for normally retaining the strip entirely within the surface ofthe sash, and an independently reciprocable pin for engaging said stripand forcing it beyond the surface vof the sash, said pin having a headnormally ush with the inner surface of the sash.

5. In a window sash, the combination ofa pivoted holding strip adaptedto extend beyond. the surface of the sash, a spring for normallyretaining the outer side of said strip flush with the correspondingsurface of the sash, said strip having an integral projection inside thesash, and a pin having a lost-motion connection with said projection andmounted to slide within the sash, said pin having a head, and a springfor keeping said head normally Hush with the inner sur face of the sash.

' 6. In a window sash, having a chamber therein near the bottom andprovided with a IOO IOS

IIO

downwardly extending projection in said chamber iush with the outerSurface of the sash, the combination of a holding Strip pivotallyconnected with the sash at a point below and inside of the downwardlyextending projection, a spring located above the pivotal point of saidStrip for normally holding the outer surface of the strip flush with theouter surface of the sash, said strip having a notch in which saidprojection fits when the strip is held flush with the sash by saidspring and u'th which said projection engages to form a tight oint whenthe strip is forced outwardly, and means for forcing the strip outwardlywith its lower edge beyond the surface of the sash.

7. In a Window sash, the combination of a pivoted holding Strip locatedon the outside of the sash and adapted to project from the surfacethereof, a spring located above the pivot of the holding strip fornormally retaining said holding strip within the surface of the sashland a push button adaptedV to engage the holding strip below its pivotto force its lower end outwardly.-

In testimony whereof I have hereunto set my hand, in the presence oftwo'subscribing witnesses.
